I suspect this could have come with a bit more explanation of what "off-CPU profiling" means.
It seems to be "account time when process was scheduled away to caller", but I had to go look at the commits to figure that out.
Partly unrelated side note: I've occasionally looked for "useful perf recipes". Not from kernel developers, but from people who solved real performance problems using perf, giving useful examples.
